Honestly, this topic could go on forever. The main reason i have lost interest in it is because there has been zero proof (from what i can see) of how traction is affected when your tire is at sidewall. Mine have been at 50psi (44 max) for the past year and i have noticed and measured no uneven wear. I have however noticed the wheels bouncing over bumps while braking and the resulting loss of grip. So i think i'll drop off the pressure a little so my shocks can keep up with the bumps in the road.
I've always ranted a bit on this subject but i feel an about face is in order.
In the lab, traction may not suffer at higher pressures but my roads are far from lab conditions and my shocks can't keep up with them. 44psi it is from now on then!
